As you know, since you were there, we have done the DATW in small and larger groups in the past and generally, I tend to share drinks. Normally, in a group of 6 or more, you can't get more than 2 people to really agree on which drink they want to order in each country. I know you and I shared at least one (China maybe?) and I shared other ones with Jim, Thommy, Sean, Kryss, and my brother (since Mike was mostly drinking beer).
With the splitting of the cost, we were really buzzed by the time we got to Canada (pics to prove it) but we were all still coherent. I think I personally spent around $60 on drinks, but again, I know we were all sharing, and I'm not counting Mike's beers in that total, since he had a margarita in Mexico, then beers in Norway, Germany, America, Morocco, UK, and Canada.
I can't wait to do it again. June it is.
